Detail of Frequency Band

Band reserved for non-civil utilisation. If civil utilisation is also stated with priority, the band is being used equally with civil utilisation on the basis of coordination.

Non-civil stations can use the band with subsidiarity to civil ones (which use the band with priority), but must not interfere and do not have rihgt to protection against interference by civil utilisation.

Non-civil stations cannot use the band.

The following bands are identified for use by high-density applications (HDFSS) in the fixed-satellite service:
17.3 – 17.7 GHz (space-to-Earth) in Region 1,
18.3 – 19.3 GHz (space-to-Earth) in Region 2,
19.7 – 20.2 GHz (space-to-Earth) in all Regions,
39.5 – 40 GHz (space-to-Earth) in Region 1,
40 – 40.5 GHz (space-to-Earth) in all Regions,
40.5 – 42 GHz (space-to-Earth) in Region 2,
47.5 – 47.9 GHz (space-to-Earth) in Region 1,
48.2 – 48.54 GHz (space-to-Earth) in Region 1,
49.44 – 50.2 GHz (space-to-Earth) in Region 1,
And
27.5 – 27.82 GHz (Earth-to-space) in Region 1,
28.35 – 28.45 GHz (Earth-to-space) in Region 2,
28.45 – 28.94 GHz (Earth-to-space) in all Regions,
28.94 – 29.1 GHz (Earth-to-space) in Region 2 and 3,
29.25 – 29.46 GHz (Earth-to-space) in Region 2,
29.46 – 30 GHz (Earth-to-space) in all Regions,
48.2 – 50.2 GHz (Earth-to-space) in Region 2.
This identification does not preclude the use of these bands by other fixed-satellite service applications or by other services to which these bands are allocated on a co-primary basis and in RR does not establish priority among users of the bands. Administrations should take this into account when considering regulatory provisions in relation to these bands. See Resolution 143.
